it looks like i have enough clearance but i dont know. I have the tires now, putting them next to the wheels on the car now but its hard to tell if theyll work. Hopefully the tire guys at NTB can tell me they definitely fit before they put them on. If the tires are mounted they cannot be exchanged by tire rack.
Agree with JBert and his findings. I dont believe you will have any issues after looking at your picture, but I have not bought aftermarket wheels(yet) for my S550. One thing to keep in mind - I've heard Michelins tend to run a little wider than advertised, and I tend to agree from my experience.
